I was out and about today for work, I saw hundreds of people, and two masks. Rural Indiana largely ignored mandates, with the smaller cities mostly playing along, barely half-heartedly.
Since election time however, most everybody's been done with it. Like other places, people are tired and want normalcy. With the idiots in charge, and rhinos being outed everywhere, even fewer people have patience like before.
It's been beautiful, mid-70s, and not many people care about masks.
For myself, I talked my mother out of getting the vaccine with evidence from everywhere. My dad still wants it, but he will come around eventually.
They're flying this month for the first time in over a year, both retired. Nervous about getting covid-19, they still haven't got it, it's understandable, they're old. :-)
Your parents could get some HCQ and ivermectin before traveling if they like from americasfrontlinedoctors.com. I came down with something recently that has some symptoms similar to the Wuhan Flu so I called and got some. That will help them if they come down with anything.
